<h2>DESCRIPTION</h2>

This module is designed to unregister raster, 3D raster and vector map
layers from space time datasets and the temporal database.

<p>
Map layer that should be unregistered from the temporal database can be
specified as a list of comma separated map names or using a text file,
that contains one map layer name per line. By default the map type that
should be unregistered is set to raster. The option<em>type</em> must
be used to specify 3D raster or vector map layer types.

<h2>INPUT FILE FORMAT</h2>

Specification of map names:
<div class="code"><pre>
a1
a2
a3
a4
a5
a6
</pre></div>

<h3>NOTE</h3>
In case the <em>input</em> option is used to specify a space time dataset
the maps are only unregistered from the space time dataset, but not from the
temporal database. The reason is that maps can be registered in
multiple space time datasets and there is a need to
unregister them from a specific STDS without affecting other STDS.

<h2>EXAMPLE</h2>

In this example a precipitation map it is registered into temperature
dataset, so the wrong map will be unregister.

<div class="code"><pre>

t.register -i type=raster input=tempmean_monthly@climate_2009_2012 \
    maps=2012_01_precip \
    start="2013-01-01" increment="1 month"

# We unregister raster map 2012_01_precip from a space time dataset,
# the raster maps are still present in the temporal database
t.unregister type=raster input=tempmean_monthly@climate_2009_2012 maps=2012_01_precip

# We unregister raster map 2012_01_precip from the temporal database, hence
# the time stamps are removed
t.unregister type=raster maps=2012_01_precip
</pre></div>
